Its very hard to put a dollar figure on capital intensity, as there are different types of projects.
Generally 90% the cost of green hydrogen is electricity, so buying from a 3rd party reducing the project complexity.

• Type 1 - Buy renewable electricity from 3rd party source. Capital intensity is low, just electrolysers, water and storage. Smallish plant. This is what we are doing in Norway, Queensland etc.
• Type 2 - Build renewable electricity from solar/wind/hydro Capital intensity is high. This is the plan for South America, some of Africa.,

Lets say each 5MW PEM is $1,000,000 or $200,000 per MW.
Please review the table below, but I see $1.5 Billion capex for 1 Billion KG per year.

In a report from February, financial consultant EY put the average cost of alkaline electrolysers at $700-1,100 per kW ($700,000-1.1m per MW) — around three to five times higher than the average $210,000 per MW in the Energy China tender.And it put the average cost of PEM electrolysers at $1,200-2,000 per kW ($1.2-2m/MW) — more than double the average $630,000/MW at the Chinese auction.The International Energy Agency says the current average price of alkaline electrolysers is $500,000-1.4m/MW, with PEM at $1.1-1.8m/MW.
